Take the ferry Memorial Day weekend through Columbus Day to this primitive Lake Michigan island where no vehicles are allowed. This unique park features the Pottawatomie Lighthouse as well as stone buildings built by a wealthy inventor who owned the island between 1910 and 1964. Rock Island offers rustic, walk-in campsites, hiking trails, a swimming beach and miles of shoreline to explore.
